16GB DDR4 3200 SO-DIMM

This Patriot Signature Line module is a 260-pin DDR4 SO-DIMM rated at 3200 MT/s (PC4-25600) with CL22 timings of 22-22-22-52 and a standard 1.20 V operating voltage. It is an unbuffered, non-ECC stick designed as a straightforward plug-and-play memory upgrade for compatible laptops.

Laptop owners adding or replacing memory

Builders whose systems require registered or ECC modules cannot use this unbuffered, non-ECC design. Users needing speeds above 3200 MT/s or lower CAS latency than CL22 should consider other options. The single 16 GB density suits one slot; buyers needing more total capacity must verify available slots.

DDR4 3200 CL22 specification

The decisive figure is the DDR4 3200 (PC4-25600) speed paired with CL22 latency; the laptop must support this exact data rate and timing for the module to run at its rated performance. The 260-pin SO-DIMM form factor and 1.20 V voltage are standard for DDR4 laptops, but the speed and latency combination determines whether this is the correct part.

Questions about this item

Does the 3200 MHz speed stay stable during long workloads?

The module is rated for DDR4 3200 (PC4 25600) at CL22 timing and 1.20 V, so it maintains that frequency under standard laptop thermal limits.

How much heat or fan noise does this 16 GB stick add?

Unbuffered DDR4 at 1.20 V runs cool; it adds minimal heat and no audible noise beyond the laptop’s existing cooling.

Will this 260-pin SO-DIMM fit my laptop’s slot?

It requires a DDR4 SO-DIMM slot with 260 pins; most laptops from the last few years use that exact interface.
